The temperature on Mercury's surface fluctuates more widely than that on the surface of any other planet. It can vary by 649 degrees Celsius (1,168 degrees Fahrenheit).
Outer Solar System. The planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.
